An image may or may not occur, help with workaround

While I run my automation, there are 3 images that pop up randomly, if they do show up my program stops doesn't know what to do and nothing progresses.

I want to know how to use a command like while exists, while not exists, if, or on-appear.

This way my program can run, and if the image does show up it will take an action and progress through to the rest of the automation.

Let me know your thoughts.
